TYPEWRITING .MACHINE To all whom it may concern:

Be it known that I, GEORGE GoULD GOING,

a citizen of the United States, residing at Middletown, in the county ofMiddlesex and State of Connecticut, have invented Certain new and usefulImprovements in Typewriting Machines, of which the following is a full,clear, and exact description, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to typewriting machines, and more particularly toimproved type actions thereof.

It is an object of the invention to provide an improved type actionincluding a bodily movable type carrier and force-transmitting anddirection-and speed-controlling connections thereto, to permit rapidoperation and effect printing substantially without noise.

It is a further object to provide a practical and efficient type actionwherein the type head'has a relatively long movement from retracted toprinting limits while the type carrier has a shorter bodily movement,whereby an increased number of the actions can be arranged in an arc inadvance of the platen, but without materially extending thefore-and-a-ft dimension of the machine.

Another object is to provide a simple and improved type action havingfeatures of structural superiority and functional advantage.

Other objects and advantages will be in part noted hereinafter inconnection with the following description of the accompanying drawings,which illustrate an exemplary embodiment of the invention. and in whichFigure 1 is a side view of the improved type action with certain of theassociated parts of the machine, and

Figure 2 is a similar view showing the parts, of the type action inprinting position, that is, at the end of the printing stroke.

As illustrated. the respective key levers 1 are pivotally mounted att-he rear ends on a fulcrum 2, being urged upwardly by a coil spring 3.Each key lever is connected through a link 4, adjustable 1n length, tothe fore end of the horizontal arm ofv a bell crank lever 5,the latterbeing pivoted at 6 on a downwardly and forwardly projected arm 7 of asupporting plate or bracket 8. Bracket 8 further pivotally supports a.link 9' at the o tally connected at 20 to the `link 21 in turnpiv'otally Application med April 23, 1921. serial 110.4641148.

rear point 10, a link 11 at the top point 12, and a sub-lever 13 atfront point 14. Lever 13 has attached to the lower end thereof a plate15 provided with a cam edge against which the cam edge 16 of thevertical arm of the bell crank 5 contacts and works. The lever 13 at itsupper end is pivotally connected at 17 to an element 17, having anenlarged or weighted portion 18 at one (front) end and having itsopposite (rear) end connected at 19 to an oil-set portion of link11,`the freev end of the latter being pivfore end of a connected at 22to a bodily movable type carrier 23. Link 9, pivoted at its lower end tosupporting plate 8, is also pivotally connected at 24 to the typecarrier 23. The carrier itself comprises a. straight end. portion whichcarries the type head 25 and an angular portion provided with a cam slot26 receiving the headed pivot stud 27 fast on a rigid arm of the support8. Movement is imparted to the type carrier 23through the link 21, whilethe path of movement of the type head 25 of the carrier 23 is in turncontrolled by the link 9 and the pin and slot connection 27, 26.

In operation, as the key lever l is depressed from the Figure 1position, bell crank 5 is rocked to swing lever 13 about its axis ofmotion 14 and at anA accelerated speed due to the rolling contactbetween the edge 16 of the vertical arm of the bell crank and the edge15 of the lower end of the lever 13; that is, the point of contactprogresses away from the axis 6 and towards the axis 14 as the key leveris depressed, to rapidly accelerate movement of the upper end of thelever 13 which carries the link 17 and the weighted portion 18. Movementof the type carrier 23 is contemporaneously effected through the link 17to link 11 to link 21. On account, however, of the link 9 and the pinand slot connection 27 26, the course of movement of a given point 30 ofthe type head 25 is parabolic, as shown in dotted lines, Figure 2. Theface of the type head, moreover, on account of the same conditions, ischanged' from horizontal in retracted position to vertical in printingposition. Towards the end of the ystroke of the type carrier, the lowerportion of the cam slot 26 co-acts with the pin 27 to insuresubstantially a straight line thrustl of the carrier towards the piatento effect printing. This final movement, moreover. is effected by theextension into substantial parallelism of the links 11 and 21, so thatthe ivotal points 12, 2O and 22 are in line,the inks mentioned thusacting in the manner of a toggle to decelerate the speed of the typehead and augment the effectiveness of the power transmitted thereto,which is further augmented by the contemporaneous alignment of thesub-lever 13 with the link 17 connecting-the same to the link 11, -thatis, the points 17', 19 and 14 are moved in line as the toggle links 11aad 21 are also extended. The final movement of the type carrier is thusaccomplished througha considerable leverage, insuring forceful pressureprinting at the end of the type head strok ,f

Such final movement of the type carrier is effected by the weighted end18 ofthe link 17, this weight serving during initial depression of thekey leverto acquire and store energy, which energy is expended af;k

ter arrest of the key lever by continuance of the swinging movement ofthe weight 18 and the resultant continued movement of the type carrier.The key lever is stopped in its down stroke, (Fig. 2) by Athe upper end16 of lever 16 contemporaneously con' tacting with the heel 15 of plate15 where the edge is concaved instead of convexed. In practice the keylever stroke is actually limited when the end of lever 16 reaches the Ypoint of reversed curvature, that is from convex to concave, ofthe edgeof plate 15 and the point mentioned is preferably located so that thekey is slightly impelled upwardly as the type-head moves its final, say,one-eighth inch toward printing limit. By the same means, if the key isforcibly held all the way down, the type-head, isA

thereby held slightly away from the platen. The spring 3 serves tore-elevate the key lever and a spring 32 stretched between fixed point33 on the bracket 8, and a mevable point 34 on the lever 13 or otherwisesuitably Ypositioned and connected as desired, serves to restore theother movable parts of the action to retracted position. Thisrestoration is further facilitated and expedited by the co-operation ofan off-set arm 35 on the sub-iever 13, acting on the printing stroke ofthe type carrier to engage and actuate a universal bar 36, the re-actionbetween these parts at the protracted limit of the type carrierhastening the initial -impulse of the parts to return to normalposition.

It will be noted that the stroke of the type carrier 23 is' limited bythe links 11 and 21 substantially independently of Vthe platen.Furthermore, as vthe type carrier, link 11, link 9, bell crank 5 andsub-lever magnete 13 are all mounted at relatively fixed positions onthe supporting bracket plate 8, fore and aft adjustment of the latter(permitted by adjusting screw 37 and set screw 38) serves to govern thethrow of the type carrier with close accuracy for the best print= ingresults. Moreover, it is to be particularly noted that while thepathtraversed, for example by the point 30 in the type head, isrelatively long, the movement o'f the parts along the first and majorportion of the distance is extremely rapid, and that as thepropelling/force of the type carrier is shifted from the key Vlever(when end 16 contacts with heel 15') to the energy storing means 18, thespeed of the type carrier is abruptly decreased but without actual stop#page, without shock and with, moreover, 4

of the movement into alignment of the levers 13 and 17 on the one handand the links 11 and 21 on the other. It is to be noted, also, that theretracted position of the type carriers with the relatively long path ofpoint 30 and the relatively short path of point 22, or a majorl rotaryand minor bodily movement of the type carrier 23 enables a segmentdisposition thereof about an arc having a considerable radius from theprinting point, and consequently a suflicient number of the typecarriers in this arrangement is permitted to have connection with acorresponding number of key levers whereby a single shift machine ispermitted; that is, each type head need carry only two type characters.

It is to be understood, also, that the ems bodiment of the inventionillustrated is susceptible to certain modifications without departurefrom the scope of the invention and without sacrifice of theattendantand major features of advantage herein noted and resident inthe improvement.
